MOLD FOR MACHINES FOR MAKING HOLLOW GLASSWARE.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed June 25, 1906. Serial No. 323,371.

To all whom it may concern:

Be it known that I, JEAN WOLF, manager of a glass-works, a subject of the German Emperor, and resident of Meister Gerhardtstrasse 6, Cologne, Germany, have invented certain new and useful Improvements in Molds for Machines for Making I-Iollow Glassware, of which the following is a specification.

The invention relates to machines for the manufacture of hollow glass-ware, in which the pressing and blowing of the glass follow one another uninterruptedly.

The invention consists of first, a new arrangement of the press-mold and the blowmold of such machines, and secondly a new arrangement of means for moving the blowmold. The press-mold is firmly fixed on the standard; the blow-mold can with the aid of suitable devices be moved upward and downward. In the lowest position the blow-mold is pushed over the press-mold, from which it is taken off by the upward movement.

My invention is illustrated by the accompanying drawing.

The same numerals denote the same parts in both figures.

Figure 1 is a side view and partly a vertical section of the machine according to the Present invention, showing the blow mold owered and the machine therefore ready for pressing. Fig. 2 shows a similar view of the machine with the blow-mold raised. In this position the machine is ready for blowing.

On the platform 1, which can be provided with rollers 2, the standard 3 is fixed. This standard acts as carrier for all parts of the pressing and blowing arrangement. On the ower part of the standard 3 the frame 4 is situated, which can be made to turn around the standard 3. The frame 4 can be fastened firmly to the standard by means of the screw 5. The frame 4 carries the pressmold 6 and the blow-mold 7. The pressmold rests fixedly on the stage 8, which is suitably adapted for the purpose. This stage 8 is fixed on the frame 4 by means of screws 9 or the like. It is obvious that the press-mold'6 cannot be moved either upward or downward. The blow-mold 7 rests on the plate 10, which is firmly attached to the support 11. Under this support there is a rod 13, which goes through the holes 14 of the frame 4. On the rod 13 a pin 15 projects sidewise which is adapted to move in head 44 has been allowed to the slot 16 of the slide 17. The slide 17 moves forward and backward in the frame 4.

I This slide is connected at 18 with the lever 19 which is by means of the link 20 jointed at 21 to the frame 4. its free end a handle 23. On the slide 17 there is also the support 24 for the bottom 25 of the blow-mold 7 whichenters the latter through the opening 26 as soon as it moves upward.

The blow-mold 7 is made up in the well known manner of two parts which are opened and closed by means of the handles 27. On the standard 3 there is also the attachment 28 provided for the two arms 29 and 30, which are respectively hinged at 31 and 32. These two arms are parallel to one another and are forked at their free ends. They support the blow-head by means of the joints 33 and 34 respectively. The arm 29 is connected at 36 with the rod 37; the other end. of this rod 37 is connected at 38 with the lever 39 which is provided with a pedal 40. By pressure on the pedal 40, the blow-head the rod 37 is tightened. When. the pedal 40 is released and so the lever 39 the blow-head is automatically raised by the spring. Farther on the standard 3 the support 42 for the press-head 44 is situated. This support swings sidewise, and has a collar 46 through which the rod passes vertically. At the bottom of the rod the press-head 44 is fixed.

47 is a hand-lever for pressing down the press-head.

48 is a spring situated around the rod which automatically Works the upward. movement of the press-head 44.

The working of the described. machine is as follows z-On the commencement of work the mold has the position shown in Fig. 1. The blow-mold 7 is lowered and pushed over the press-mold 6. In this position the molten glass is brought into the mold, and is then pressed by the lowering of the press-head. As the press-mold cannot be pressed away from the blow-mold by the pressing down of the press-head, so there is between the two molds no crack through which the molten glass can penetrate. The formation of projecting ribs on the outside of the glass object is therefore avoided. Such outside markl ings take place in the known machines in which the press-mold is arranged movable, but the blow-mold fixed. After the pressrise by releasing The lever 19 has at 35 can be lowered, whereby a spring 41 on I oi the handles 27 and ever 39, the rod 37, the arms valve, arranged the lever 47, the arm 42 carrying the presshead is turned sideward toward the standard 3. By means of the lever 19 the slide 17 is pushed so that it has the position shown in Fig. 2 the pin 15 therefore moves upward in the slot 16 of the slide 17 so that the rod 13 with the support 11 of the plate 10 and blowmold 7 is raised. At the same time the bottom 25 enters through the opening 26 under the blow-mold .(Fig. 2). The pressed glass material now hangs in the blow-mold. The aedal 40 is then pressed down so that the l and 30, are operated bringing down the blow-head 35 into position. The blow-head 35 fits on the blow-mold 7, when at the same time the in well-known manner, opens. The compressed air entering from the blow-head blows out the previously pressed glass to the form of the mold. The arms 29 and 30 hold the blowhead, so that its lower surface 19 fits exactly horizontally on the blow-mold 7. 19 is not fixed, but lies on the link 20. It is thus provided that the slide 17 may move in a straight line and is protected from getting jammed. When the pedal 10 is released the blow-head raises itsel'l' automatically under the influence of the spring 11, into the position shown in 1. blow-mold 10 are then opened out by means the completed glass object taken out. ll the handle 23 of the lever 19 is pulled, then the movable parts of the slide and mold come from the position shown in Fig. 2 into the position Fig. 1. The pivots in this way so arranged, that alter a short pull on the handle 23 of the lever 19, the blow-mold 7 sinks automatically by its own weight. On this account the time between the pressing and blowing'operations is shortened and the producing capacity of the machine increased.

1 herewithpoint out that the new mold may also be applied to machines, other than those of the art described. The new arrangement of the press-mold and blow-mold can also find application in all suitable kinds of machines; especially in such which have molds near or behind one another.
